For anyone who does not know yet... if you don't attack the bosses you will get no rewards, no matter how hard you worked your fingers off keeping people alive as a healer.
It does not matter if you are the only person in the entire 10 person roster with heals / shields / rezzes. It does not matter how many dozens of times you saved people from dying or revived them when they got one hit. It does not matter if your presence was the only reason that queue succeeded instead of failing. You will still not be mentioned in the contributors list and will not see any ! reward location.
It is completely lame that the idiots at Cryptic would deliberately code something that hurts the one person on the team that was truly the difference between a win and a loss.
